The Grand Church of the Winter Palace (Russian: Cобор Спаса Нерукотворного Образа в Зимнем дворце) in Saint Petersburg, sometimes referred to as the Winter Palace's cathedral, was consecrated in 1763. It is located on the piano nobile in the eastern wing of the Winter Palace, and is the larger, and principal, of two churches within the Palace. A smaller, more private church was constructed in 1768, near the private apartment in the northwest part of the wing. The Grand Church was designed by Francesco Rastrelli, and has been described as "one of the most splendid rooms" in the Palace.
